Astaroth

The so-called "Crowned Prince of Hell", as well as the founder of Tokyo Babel and Pandora.

As the current highest-ranking official at Pandora, he has taken up residence at the principal's office. Possibly owing to his origins being related to the goddess Ishtar, he emanates a certain aura of androgyny. With no more archdemons to oppose him, he now rules as the de facto leader of Pandora, though one cannot help but question the point of reigning over a ruined world. Still, he most likely gets a genuine kick out of the situation.
